APT Problems

See below for hints on what to do if your APT doesn't run.

For each problem in an APT set, complete these steps by the due date

• first test it and ensure your program runs
• test and refine your code until you get all-green, or you've had enough and are stopping
• check your grade on the submission page by clicking on check submissions near the top
• then fill out the REFLECT form for each APT you do to give us feedback on that problem and to certify that you understand the code for that APT.

In solving APTs, your program should work for all cases, not just the test cases we provide.

All submissions for APTs will be via net-id. The submission with the most points will count for grading. Please submit the REFLECT to ensure we have an understanding of your work. The REFLECT is required if you collaborated, and encouraged for everyone.

Problems Running an APT? Some Tips!

• Make sure you have the correct file name, file names are case-senstive and in .java -- do not submit a .class file.
• Make sure you have the correct class and method name.
• Always start with return 0 or return "" or return new String[0] to see if your function name and file are correct. You won't have the correct answer but you should have the red and green boxes.

• Do you have the correct type of value to return? If the function is suppose to return an integer, are you returning an integer?

• If you are getting timelimit exceeded and have tried all the things above, put in a print statement at the top of your function such as

    System.out.println("starting function")
  

  When you run it, does that show up?
• If you are getting blank and green boxes but cannot figure out what is wrong with your code, then try copying your code into Java Tutor. You will also need to add a statement to call the function with some input. Then you can trace through it in Java Tutor and see the values of variables.
